The Edinburgh Postnatal Depression Scale: validation in a Norwegian community sample

Psychometric properties of the Decisional Conflict Scale in a sample of perinatal women with depressive symptoms: A study in Portugal and Norway

OBJECTIVE

To assess the psychometric properties, i.e., reliability and construct validity of the 16-item Decisional Conflict Scale (DCS) and sub-scales in women with perinatal depressive symptoms in Norway and Portugal.

METHODS

We included 415 women in Portugal and 163 in Norway (≥18 years) who were pregnant or had given birth in the last 12 months and presenting with active depressive symptoms. Women replied to the original DCS items. We conducted confirmatory factor analysis, estimated internal consistency reliability, and examined factorial invariance across country, perinatal status, and treatment uptake.

RESULTS

The DCS factor model had good fit to the data, with all items loading significantly on their respective factor (.585 to .958). There was configural invariance of the DCS across countries, treatment, and perinatal status. The internal consistency of the total DCS (Cronbach's alpha) was .958, and for the subscales it ranged from .798 to .947.

CONCLUSIONS

The DCS is a valid and reliable measure of the decisional conflict in women with perinatal depressive symptoms in Portugal and Norway.

PRACTICE IMPLICATIONS

Measuring the extent of decisional conflict regarding treatment and the effect of multiple interventions towards its reduction, is critical to facilitate the decision-making process of women with perinatal mental illness.

Multiple Risk in Pregnancy- Prenatal Risk Constellations and Mother-Infant Interactions, Parenting Stress, and Child Externalizing and Internalizing Behaviors: A Prospective Longitudinal Cohort Study from Pregnancy to 18 Months Postpartum

Multiple risk is associated with adverse developmental outcomes across domains. However, as risk factors tend to cluster, it is important to investigate formation of risk constellations, and how they relate to child and parental outcomes. By means of latent class analysis patterns of prenatal risk factors were identified, and relations to interactional quality, parenting stress, and child internalizing and externalizing behaviors were investigated. An array of prenatal risk factors was assessed in 1036 Norwegian pregnant women participating in a prospective longitudinal community-based study, Little in Norway. Mother-infant interactions were videotaped and scored with the Early Relational Health Screen (ERHS) at 12 months. The Parenting Stress Index (PSI) and Infant-Toddler Social and Emotional Assessment (ITSEA) were administered at 18 months. First, we analyzed response patterns to prenatal risks to identify number and characteristics of latent classes. Second, we investigated whether latent class membership could predict mother-child interactional quality, parenting stress, and child internalizing and externalizing behavior after the child was born. Results revealed three prenatal risk constellations: broad risk (7.52%), mental health risk (21.62%) and low-risk (70.86%). Membership in the broad risk group predicted lower scores on interactional quality, while membership in the mental health risk group predicted less favorable scores on all outcome measures. Prenatal risks clustered together in specific risk constellations that differentially related to parent, child and interactional outcomes.

Partner support for women's antidepressant treatment and its association with depressive symptoms in pregnant women, mothers, and women planning pregnancy

PURPOSE

To examine the association between partner support for women's antidepressant treatment and depressive symptoms in pregnant women, those planning pregnancy, and mothers who ever used antidepressants.

METHODS

We included 334 women (n=44 planners, n=182 pregnant, n=108 mothers) ever treated with antidepressants within the HEALTHx2 study, a web-based cross-sectional study conducted across Norway in June 2020 to June 2021. The Edinburgh Postnatal Depression Scale and two questions of the Patient Health Questionnaire measured depressive symptoms, by degree of severity and for depressed mood, anxiety, and anhedonia sub-dimensions. Partner support was measured using one item from the Antidepressant Compliance Questionnaire. Association was estimated via unadjusted and adjusted linear and logistic regression models.

RESULTS

Being unsupported by the partner was associated with increased odds of reporting moderate-to-very-severe depressive symptoms in mothers (adjusted odds ratio (aOR), 3.57; 95% confidence interval (CI), 1.04-12.19) and pregnant women (aOR, 3.26; 95% CI, 0.95-11.14), relative to being supported. Pregnant women (adjusted mean difference (β), 0.76; 95% CI, 0.14-1.38) and mothers (β, 0.93; 95% CI, 0.23-1.64) with no support for their antidepressant treatment presented greater symptoms of anhedonia; for women planning pregnancy, this association emerged in relation to anxiety symptoms (β among non-users of antidepressant, 2.58; 95% CI, 1.04-4.13).

CONCLUSIONS

Partner support for women's antidepressant treatment may play a key role in depressive symptoms severity and the subtypes of anhedonia and anxiety, among women planning pregnancy, pregnant women, and mothers. This highlights the importance of partner inclusion in the complex decision-making process for antidepressant treatment around the time of pregnancy.

Association between adverse childhood experiences and perinatal depressive symptoms: a cross-sectional analysis of 16,831 women in Iceland

Emerging data suggest that certain adverse childhood experiences (ACEs) are associated with perinatal depression (PND). However, few studies have comprehensively assessed the cumulative number and types of ACEs and their association to PND. We conducted a cross-sectional analysis among 16,831 female participants from the Stress-And-Gene-Analysis (SAGA) cohort in Iceland, 2018. ACEs were surveyed with the World Health Organization ACE-International questionnaire, while PND symptoms were assessed using the Edinburgh Postnatal Depression Scale (lifetime version). We, while adjusting for confounding factors, estimated the prevalence ratio (PR) of PND in relation to total number of ACEs using the Poisson quasi-likelihood model and further performed analyses for type-specific ACEs. At a mean age of 44 years (SD ± 11.1), 6,201 (36.8%) participants had experienced probable PND. Total number of ACEs was positively associated with PND (PR 1.11 per ACE, 95% CI: 1.10-1.11), also among women without any psychiatric comorbidities (PR 1.13, 95% CI: 1.11-1.14). PRs increased in a dose-response manner with the number of ACEs (P for trend < 0.001); women that endorsed 5 or more ACEs were twice as likely to have experienced PND (PR 2.24, 95% CI: 2.09-2.41). All ACE types (n = 13) were associated with PND, with most pronounced association for emotional neglect by a guardian (PR 1.53, 95% CI: 1.47-1.59). Our findings suggest a positive association between number of ACEs and PND symptoms. If our results are confirmed with prospective data, healthcare providers need to be alert of the risk of PND among expecting mothers with history of ACEs.

Treatment options and their uptake among women with symptoms of perinatal depression: exploratory study in Norway and Portugal

BACKGROUND

Perinatal depression is the most undertreated clinical condition during the perinatal period. Knowledge about women's decision-making in seeking and receiving treatment is scarce.

AIMS

To investigate and compare treatment option uptake in perinatal women with depressive symptoms in Portugal and Norway, and to identify sociodemographic and health-related factors associated with treatment uptake.

METHOD

Participants were women resident in Portugal or Norway (≥18 years) who were pregnant or had given birth in the past 12 months, who presented with active depressive symptoms (Edinburgh Postnatal Depression Scale score ≥10). In an electronic questionnaire, women reported treatment received and sociodemographic and health-related factors.

RESULTS

The sample included 416 women from Portugal and 169 from Norway, of which 79.8% and 53.9%, respectively, were not receiving any treatment. Most Portuguese women were receiving psychological treatment, either alone (45.2%) or combined with pharmacological treatment (21.4%). Most Norwegian participants were receiving only pharmacological (36.5%) or combined treatment (35.4%). Compared with the Portuguese sample, a higher proportion of Norwegian women started treatment before pregnancy (P < 0.001). In Portugal, lower depressive symptoms and self-reported psychopathology were significantly associated with higher likelihood of receiving treatment.

CONCLUSIONS

We found that, in both Norway and Portugal, a substantial number of perinatal women with depressive symptoms do not receive any treatment. Differences exist regarding the chosen treatment option and timing of treatment initiation in the two countries. Only mental health-related factors were associated with treatment uptake for perinatal depression in Portugal. Our results highlight the importance of implementing strategies aimed to improve help-seeking behaviours.

Video Consultations and Safety App Targeting Pregnant Women Exposed to Intimate Partner Violence in Denmark and Spain: Nested Cohort Intervention Study (STOP Study)

BACKGROUND

Intimate partner violence (IPV) during pregnancy is a public health issue with wide-ranging consequences for both the mother and fetus, and interventions are needed. Therefore, the Stop Intimate Partner Violence in Pregnancy (STOP) cohort was established with the overall aim to identify pregnant women exposed to IPV through digital screening and offer women screening positive for IPV a digital supportive intervention.

OBJECTIVE

The aim of this study was to (1) introduce the design and profile of the STOP cohort study, (2) assess the feasibility of implementing digital IPV screening among pregnant women, and (3) assess the feasibility of implementing a digital supportive intervention targeting pregnant women exposed to IPV.

METHODS

Pregnant women attending antenatal care in the Region of Southern Denmark and in Andalucía, Spain were offered digital screening for IPV using validated scales (Abuse Assessment Screen and Women Abuse Screening Tool). Women who screened positive were eligible to receive a digital supportive intervention. The intervention consisted of 3-6 video consultations with an IPV counselor and a safety planning app. In Denmark, IPV counselors were antenatal care midwives trained by a psychologist specialized in IPV, whereas in Spain, the counselor was a psychologist.

RESULTS

Data collection started in February 2021 and was completed in October 2022. Across Denmark and Spain, a total of 19,442 pregnant women were invited for IPV screening and 16,068 women (82.65%) completed the screening. More women in Spain screened positive for exposure to IPV (350/2055, 17.03%) than in Denmark (1195/14,013, 8.53%). Among the women who screened positive, only 31.39% (485/1545) were eligible to receive the intervention with only 104 (21.4%) of these women ultimately receiving it.

CONCLUSIONS

Digital screening for IPV among pregnant women is feasible in an antenatal care context in Denmark and Spain; however, a digital supportive intervention during pregnancy appears to have limited feasibility as only a minor subgroup of women who screened positive for eligibility received the intervention. More research is needed on how to best support pregnant women exposed to IPV if universal IPV screening is to be implemented in antenatal care.

Impact of the COVID-19 pandemic on women's perinatal mental health and its association with personality traits: An observational study

INTRODUCTION

The burden of perinatal mental health problems was expected to increase during the COVID-19 pandemic. We prospectively investigated the impact of the COVID-19 pandemic on the mental health of pregnant and postpartum women in Norway and explored associations with their sociodemographic characteristics and personality traits.

MATERIAL AND METHODS

Sociodemographic information and the self-reported impact of pandemic on wellbeing of pregnant women was collected using an online survey. To assess women's mental health, two validated questionnaires, the Edinburgh Postpartum Depression Scale (EPDS) and the Generalized Anxiety Disorder-7 item Scale (GAD-7), were used prenatally and postnatally. Personality traits were evaluated using HumanGuide, a web-based ipsative psychological evaluation instrument.

RESULTS

772 women were included prenatally, of which 526 also responded to the survey 4-6 weeks postnatally. The median age was 29 years, 53.6% of the women were nulliparous when enrolled, and 35.1% worked in the healthcare sector. The median EPDS (6.0; interquartile range [IQR] 3.0-10.0 vs 6.0; IQR: 3.0-10.0) and the median GAD-7 (5.0; IQR 2.0-9.0 vs 5.0; IQR 2.0-9.0) were similar pre-and postnatally. Prenatally, the proportion of women scoring ≥13 on EPDS and ≥10 on GAD-7 was 14.5% (112/772) and 21.5% (166/772), whereas the postnatal figures were 15.6% (82/526) and 21.5% (113/526), respectively. The differences were not significant (P = 0.59 and P = 0.99). Being <25 years of age, being on pre-pregnancy psychotherapy or psychotropic medication, frequent voluntary isolation, perception of maternity care not proceeding normally, avoiding seeking medical assistance due to fear of infection and having negative economic consequences during the COVID19 pandemic significantly increased the risk of both anxiety (GAD-7 ≥10) and depression (EPDS ≥13). Nullipara had a higher risk of anxiety, whereas being a healthcare worker had a lower risk. The personality trait factors Power (P = 0.008), Quality (P = 0.008), Stability (P < 0.001) and Contacts (P < 0.001) were significant predictors of depression among pregnant women, whereas the Quality (P = 0.005) and Contacts (P = 0.003) were significant predictors of anxiety.

CONCLUSIONS

During the initial phase of the COVID-19 pandemic, the prevalence of depression (EPDS ≥ 13) and anxiety (GAD-7 ≥ 10) was 14.5% and 21.5%, respectively, among Norwegian pregnant women. Certain sociodemographic characteristics and personality traits were significant predictors of depression and anxiety.

Concurrent changes in dental anxiety and smoking in parents of the FinnBrain Birth Cohort Study

We evaluated associations between changes in dental anxiety and tobacco use, adjusted for general anxiety and depressive symptoms. The FinnBrain Birth Cohort Study data, collected at gestational weeks 14 and 34 and at 3 months postpartum, were used. Questionnaires included the Modified Dental Anxiety Scale (MDAS), the Edinburgh Postnatal Depression Scale (EPDS), and the anxiety subscale of the Symptom Checklist-90 (SCL). Smoking was categorized as "stable non-smoking", "started smoking", "quit smoking", and "stable smoking". Changes in smoking and dental anxiety were evaluated "during pregnancy" (i.e., from gestational week 14 to gestational week 34) in 2442 women and 1346 men and "after pregnancy" (i.e., from gestational week 34 to 3 months postpartum) in 2008 women and 1095 men. Changes were evaluated in three smoking categories (stable non-smoking, fluctuating, and stable smoking), using data from all three time-points (1979 women and 1049 men). Modeling used repeated measures analysis of covariance. Stable smoking mothers had statistically significantly higher levels of dental anxiety (mean MDAS 12.3-12.6) than non-smoking mothers (mean MDAS 10.1-10.7) or mothers who smoked at some point during pregnancy (mean MDAS 10.8-11.5). A similar tendency was observed in fathers. However, no systematic change in dental anxiety by changes in smoking habits was observed. Those smoking during pregnancy and with high dental anxiety may need special support for smoking cessation.

Predictors and comorbidity patterns of maternal birth-related posttraumatic stress symptoms: A Latent Class Analysis

Birth-related posttraumatic stress symptoms (PTSS) place a significant burden on mothers and their families. The aim was to (1) identify differential profiles of maternal birth-related PTSS; (2) determine the predictive value of established risk factors; (3) examine comorbidity patterns related to depression and anxiety symptoms. As part of the Norwegian Ahus Birth Cohort, 2,088 (expectant) mothers completed self-report questionnaires from 17 weeks of gestation to 2 years postpartum. The Impact of Event Scale was used to assess PTSS 8 weeks after birth. Latent class analysis revealed four latent classes: a High birth-related PTSS class (4%), a Moderate birth-related PTSS class (16%) particularly characterized by endorsement of intrusion symptoms, a Mild birth-related PTSS class (47%), as well as a No birth-related PTSS class (33%). We found similar (younger age, worse subjective birth experience, higher fear of childbirth) and differential predictors (prior posttraumatic stress disorder, lower education, birth complications). Women classified with High, Moderate, or Mild birth-related PTSS showed higher depression and anxiety symptoms compared to women with No birth-related PTSS. A considerable number of mothers experienced birth-related PTSS, most on a subclinical level, but these women still showed signs of mental distress 2 years postpartum, calling for more universal prevention approaches.

Quality of life in Norwegian pregnant women and men with pregnant partners, and association with perception of sleep and depressive symptoms: a cross-sectional study

BACKGROUND

Pregnant women and men with pregnant partners experience variations in quality of life (QoL) during pregnancy, a period characterized by physical, psychological, and social changes. Pregnancy is associated with reduced QoL, depressive symptoms, and sleep problems. This study aimed to: (1) determine whether Norwegian pregnant women and men with pregnant partners differed in QoL levels in the third trimester of pregnancy; (2) determine whether the relationship between perception of sleep and QoL is moderated by depressive symptoms, when analyzed separately in pregnant women and men with pregnant partners; and (3) determine whether selected possible predictive factors were associated with QoL when stratified by level of depressive symptoms, in pregnant women and men with pregnant partners separately.

METHODS

A cross-sectional study conducted between October 2018 and January 2020 included 228 pregnant women and 197 men with pregnant partners in the third trimester of pregnancy. The age range was 22-50 years. QoL was assessed using the World Health Organization Quality of Life Questionnaire brief version, depressive symptoms using the Edinburgh Postnatal Depression Scale, and perception of sleep by a single item. Data were analyzed in SPSS version 28 using descriptive statistics, the PROCESS macro for moderation analyses, and multivariate linear regression. The level of statistical significance was p < 0.05.

RESULTS

Pregnant women reported significantly lower QoL scores on the physical health and psychological domains than the men with pregnant partners. Our data did not reveal any moderating effect of depressive symptoms on the relationship between the perception of sleep and QoL. Depressive symptoms in the pregnant women were found to be a significant predictor of lower QoL in all domains. In the men with pregnant partners, getting enough sleep was a significant predictor of higher QoL in all domains. In the pregnant women without depressive symptoms, higher QoL in the physical health domain was significantly associated with the perception of getting enough sleep.

CONCLUSION

Women in the final trimester of pregnancy experience poor QoL compared to the men with pregnant partners. Pregnant women with depressive symptoms have lower QoL compared to those without depressive symptoms. The perception of getting enough sleep was associated with better QoL.

Prevalence and predictive factors of depressive symptoms among primiparae in antenatal care: A cross-sectional study in the new families programme

AIM/OBJECTIVE

To estimate the prevalence and assess the strength of associations between antenatal depressive symptoms and selected possible predictive factors among women attending antenatal care for the first time at the Child Health Centre.

BACKGROUND

Evidence suggests that antenatal depression is a health problem as prevalent as postpartum depression. Antenatal depressive symptoms may persist into the postpartum period and potentially disturb the attachment between mother and family.

DESIGN

Cross-sectional.

METHODS

A sample of 228 women who participated in the New Families research programme answering a questionnaire at Week 28 of pregnancy were included. The Edinburgh Postnatal Depression Scale was used as outcome measure. Prevalence was estimated, and backward stepwise logistic regression analysis was performed to examine associations with somatic, psychiatric and social factors. STROBE checklist was followed.

RESULTS

Prevalence of depressive symptoms in this sample was 17.9%. Women reporting not sleeping enough had significantly higher odds of having depressive symptoms. Pregnant women with high relationship satisfaction were less likely to have depressive symptoms. Neither maternal age, education, previous depression, coming from a non-Nordic country nor having complications during pregnancy were statistically significantly associated with depressive symptoms.

CONCLUSIONS

High prevalence of depressive symptoms may also be present in low-risk populations. Sleep and relationship satisfaction are topics that need to be addressed during pregnancy.

RELEVANCE TO CLINICAL PRACTICE

The prevalence of depressive symptoms in this sample of low-risk pregnant women indicates that health personnel needs to be aware of depressive symptoms among women with no risk indicators. Identifying predictive factors associated with depressive symptoms may help midwives, public health nurses and general practitioners support parents. Our results indicate a potential need for screening for depressive symptoms in pregnancy and underscore the importance of involving partners in antenatal care.

PATIENT/PUBLIC CONTRIBUTION

Parents and health personnel participated in designing the New Family research programme.

E-health psychological intervention in pregnant women exposed to intimate partner violence (eIPV): A protocol for a pilot randomised controlled trial

Intimate partner violence (IPV) during pregnancy, a condition as common as obstetrics conditions like gestational diabetes, is associated with maternal and neonatal complications. Systematic detection of IPV is not well established in antenatal screening probably because the effectiveness of protective interventions has not been evaluated. E-health interventions may be beneficial among mothers exposed to IPV. Prior to performing a full-scale effectiveness trial for such an intervention, a pilot study is required to assess the feasibility of randomising a sufficiently large number of women exposed to IPV during pregnancy. The eIPV trial is a randomised pilot study nested within a cohort of consenting mothers who screen positive for IPV in the first antenatal visit at <12 weeks' gestation and accept an e-health package (psychological counselling by videoconference) in Spain and Denmark. Twenty eligible mothers from the above cohort will be randomised to either intervention or control. The intervention group will receive the e-health package as part of the cohort. The control group will be invited to accept a delay in the intervention (e-health package eight weeks later). After consenting to delay, the control group will provide comparative data without losing the opportunity of obtaining the intervention. We will determine estimates of rates of informed consent to randomization, and the rates of adherence and dropout following randomization. Qualitative interviews will be conducted to examine the women's perception about the benefit of the intervention, reasons for acceptability and non-adherence, and obstacles to recruitment, randomisation and consent. The results will inform the trial feasibility and variance of key clinical outcome measures for estimation of sample size of the full-scale effectiveness trial.

Do parental cognitions during pregnancy predict bonding after birth in a low-risk sample?

Parental bonding to their infant is important for healthy parent-infant interaction and infant development. Characteristics in the parents affect how they bond to their newborn. Parental cognitions such as repetitive negative thinking, a thinking style associated with mental health issues, and cognitive dispositions, e.g., mood-congruent attentional bias or negative implicit attitudes to infants, might affect bonding.

To assess the influence of cognitive factors on bonding, 350 participants (220 pregnant women and their partners) were recruited over two years by midwives at the hospital and in the communal health care services. Participants were followed throughout the pregnancy and until the infant was seven months old as a part of the Northern Babies Longitudinal Study. Both mothers and fathers took part. First, we measured demographics, repetitive negative thinking, attentional bias, and implicit attitudes to infants during pregnancy, as predictors of bonding two months postnatally. Second, we also measured infant regulatory problems, and depressive symptoms at two months postnatally as predictors of parents’ perception of infant temperament at five months. Robust regression analyses were performed to test hypotheses.

Results showed that mothers and fathers differed on several variables. Parity was beneficial for bonding in mothers but not for fathers. Higher levels of mothers’ repetitive negative thinking during pregnancy predicted weaker bonding, which was a non-significant trend in fathers. For fathers, higher education predicted weaker bonding, but not for mothers. Mothers’ perception of their infant temperament at five months was significantly affected by bonding at two months, but for fathers, their depressive symptoms were the only significant predictor of perceived infant temperament.

In conclusion, for mothers, their relationship with their infant is essential for how they experience their infant, while for fathers their own wellbeing might be the most important factor. Health care providers should screen parents’ thoughts and emotions already during pregnancy to help facilitate optimal bonding.

Perceived risk of neurodevelopmental outcomes in offspring related to psychotropic and mental illness exposures in pregnancy and breastfeeding: a cross-sectional survey of women with past or current mental illness

OBJECTIVES

To investigate the perceived risk of psychotropic and mental illness exposures (1) during pregnancy or (2) while breastfeeding on offspring neurodevelopment, and factors associated with this perception in women with past/current mental illness.

DESIGN

Cross-sectional, web-based study.

SETTING

Nationwide in Norway, June 2020-June 2021.

PARTICIPANTS

Women aged 18-55 years who were pregnant, recent mothers or planning a pregnancy, and had been offered antidepressants in the last 5 years.

PRIMARY AND SECONDARY OUTCOME MEASURES

Perceived risk of prenatal and breastmilk exposure to psychotropic medications and maternal mental illness on offspring neurodevelopmental outcomes.

RESULTS

We included 448 women: 234 pregnant, 146 mothers and 68 planning a pregnancy. On a 0-10 scale, women perceived antidepressants as least harmful both (1) in pregnancy (mean score 4.2, 95% CI 3.6 to 4.8) and (2) while breastfeeding (mean score 3.8, 95% CI 3.3 to 4.4), relative to antipsychotics, anxiety/sleeping medication or antiepileptics (mean score range: 6.3-6.5 during pregnancy, 5.5-6.2 while breastfeeding). Many participants were unfamiliar with psychotropics other than antidepressants. The perceived risk of mental illness exposure exceeded that of antidepressants (mean score range 5.6-5.9) in both exposure periods. Using general linear models, factors associated with greater antidepressant risk perception in both exposure periods included having lower education, non-Norwegian native language, and employment status (range mean score difference (β): 2.07-6.07). For pregnant women and mothers, there was an inverse association between perceived risk and the perceived antidepressant effectiveness in both exposure periods (range of β: -0.18 to -0.25).

CONCLUSIONS

In women with past/current mental illness, the perceived risk of antidepressant exposure on child neurodevelopment was lower than that for maternal mental illness. Other psychotropic medications were perceived as more harmful. As medication risk perception influences the decision-making regarding treatment of mental illness, pre- and pregnancy counselling should target women with characteristics associated with higher perceived risk.

The impact of diagnosed fetal anomaly, diagnostic severity and prognostic ambiguity on parental depression and traumatic stress: a prospective longitudinal cohort study

INTRODUCTION

The detection of a fetal anomaly during routine obstetric ultrasound is a potentially traumatic experience. The aim of this study is to examine longitudinally the impact of diagnosis of fetal anomaly on symptoms of depression and traumatic stress among mothers and fathers, and to examine how variations in psychological adjustment relate to diagnostic severity and prognostic ambiguity.

MATERIAL AND METHODS

In this prospective observational study conducted at a tertiary perinatal referral center, 81 mothers and 69 fathers with ultrasound findings of fetal anomaly completed the Edinburgh Postnatal Depression Scale (EPDS) and Impact of Events Scale (IES) at four time points in pregnancy (T1-T4) and 6 weeks after birth (T5). We compared this with depression and traumatic stress in a sample of non-affected parents (n = 110 mothers, 98 fathers).

RESULTS

Linear mixed effects models indicated that parents who received a diagnosis of fetal anomaly experienced higher levels of depression and traumatic stress over time, compared with non-affected parents. Depression: mean difference mothers = 4.46 ± 0.47, fathers = 2.80 ± 0.42. Traumatic stress: mean difference mothers = 20.04 ± 2.13, fathers = 12.66 ± 1.74. Parents with a more severe diagnosis experienced elevated symptoms compared with parents with a less severe diagnosis. Among mothers, prognostic ambiguity and changes in the anticipated diagnosis after birth were also associated with increased distress, regardless of whether the change was for the better or worse.

CONCLUSIONS

Diagnosis of fetal anomaly increases risk of depression and traumatic stress in expectant mothers and fathers, both acutely and over time.

Sleep patterns and psychosocial health of parents of preterm and full-born infants: a prospective, comparative, longitudinal feasibility study

Background

The early birth and hospitalization of a preterm infant in neonatal intensive care unit can produce several emotional and behavioural responses including sleep problems for parents. Few studies have explored sleep and its associations with health and HRQoL over time in this vulnerable parent population. This purpose of this study was to evaluate the feasibility of a prospective, comparative, longitudinal study of the sleep patterns and psychosocial health of preterm and full-born infants’ parents during the first postpartum year.

Methods

A prospective, comparative, longitudinal feasibility study was conducted. Parents of preterm infants were compared to parents of full-born infants to identify if there were differences in outcomes between the groups. The parents were instructed to wear actigraphs and complete sleep diaries for two consecutive weeks, and responded to a digital questionnaire covering stress, insomnia, fatigue, depression, social support, self-efficacy, and health-related quality of life. Survey data were collected at infant ages of 2, 6, and 12 months, actigraphy and sleep diary data were collected at infant age of 2 months only. Descriptive analysis was used to describe recruitment and attrition rates. Differences between completers and dropouts were analysed with a chi-square test (categorical data) and Mann–Whitney–Wilcoxon test for two independent samples (continuous variables).

Results

Between June 2019 and March 2020, 25 parents of a preterm infant and 78 parents of a full-born infant were recruited from four neonatal intensive care units and two maternity wards, respectively, in four Norwegian hospitals. Feasibility was predefined as recruiting ≥ 75 parents each of preterm and full-born infants. The target for the full-born group was reached. However, the preterm group recruitment was challenging. Actigraphs, sleep diaries, and questionnaires were evaluated as feasible for use in a future study. Attrition rates were high in both groups at 6 and 12 months. No parent-related characteristics were associated with participation at 6 months. At 12 months, dropouts had a statistically significantly lower age in the full-born group (both parents) and higher age and body mass index in the preterm group (fathers).

Conclusions

A longitudinal study is feasible; however, procedural changes, including using active methods and contacting participants, are necessary to increase the recruitment of preterm infants’ parents.

Prenatal work stress is associated with prenatal and postnatal depression and anxiety: Findings from the Norwegian Mother, Father and Child Cohort Study (MoBa)

BACKGROUND

An emerging body of research suggests that stress experienced in the workplace can have detrimental impacts on maternal mental health, including greater risk of postnatal depression. However, few longitudinal studies have examined these associations during the perinatal period. The objective of this study was to examine the associations between prenatal work stress and subsequent depression and anxiety.

METHODS

This study is based on the Norwegian Mother, Father and Child Cohort Study (MoBa), and included 77,999 employed women recruited between 1999 and 2008. The exposure variable was prenatal work stress measured at 17 weeks' gestation, using an 8-item scale examining factors including autonomy, working relationships, and work enjoyment. Outcomes included depression and anxiety at 30 weeks' gestation and 6 months postpartum, measured using the Symptom Checklist-8. Analyses comprised of unadjusted and adjusted logistic regressions.

RESULTS

After covariate adjustment, prenatal work stress was associated with depression and anxiety at 30 weeks' gestation (OR = 1.33, 95% CI: 1.19-1.49), and 6 months postpartum (OR = 1.44, 95% CI: 1.28-1.61). Most associations remained after adjustment for additional work-related variables and maternity leave.

LIMITATIONS

Work stress was measured once during pregnancy, thus variation of associations by trimester could not be investigated. Findings are reported for a sample with high socioeconomic status, and may not generalize to other populations.

CONCLUSIONS

Women dealing with work stress during pregnancy are more likely to experience subsequent depression and anxiety. Findings can inform the development of workplace strategies to support the mental health of expecting and new mothers.

Changes in maternal cortisol, cortisol binding globulin and cortisone levels following diagnosis of fetal anomaly

The diagnosis of fetal anomaly can be a major stressor to the expectant mother. Current understanding of the relationship between psychological stress and cortisol in pregnancy is limited. This study examined: (1) differences in the ratio of serum cortisol to cortisol binding globulin (SC/CBG) and cortisone levels among women with and without a diagnosis of fetal anomaly, (2) the association between self-reported stress and cortisol from mid to late pregnancy, and (3) the agreement between two different techniques for analyzing cortisol: liquid chromatography-tandem mass spectrometry (LC-MS/MS) and radioimmunoassay (RIA). Thirty-six pregnant women with a diagnosis of fetal anomaly (study group) and 101 women with healthy pregnancies (comparison group) provided blood samples and completed self-report questionnaires at gestational weeks 18-24 (T1) and 30 (T2). In the comparison group, mean SC/CBG increased from 0.341 nmol/L at T1 to 0.415 at T2 (p < .001), whereas in the study group there was no change (0.342 nmol/L at T1, 0.343 at T2). There was no difference in cortisone levels between the groups at either timepoints. There was a negative association between both depression and traumatic stress at T1, and SC/CBG at T2 (p < .05). There was no association between general distress and SC/CBG. The two methods for analyzing cortisol gave similar results, but with LC-MS/MS showing a lower detection limit than RIA. Increased cortisol with advancing gestational age is expected, thus these findings indicate that under certain conditions of severe stress there may be a suppression of maternal cortisol increase from mid to late gestation. The discrepancy does not seem to be due to differences in the metabolization of cortisol, as indicated by the similar levels of cortisone. Further research is needed in order to understand the potential underlying mechanisms limiting the expression of cortisol in response to certain types of stress in pregnancy.

Pregnant people's responses to the COVID-19 pandemic: a mixed-methods, descriptive study

BACKGROUND

Given the extent of the COVID-19 pandemic and uncertainty around the timing of its containment, understanding the experiences and responses of the perinatal population is essential for planning responsive maternity care both during and after the pandemic. The aim of this study was to explore the experiences of pregnant people and their responses to the COVID-19 pandemic, and to identify how health care providers can support this population.

METHODS

This was a mixed-methods, descriptive study with cross-sectional and qualitative descriptive components. We conducted the study between Mar. 20 and May 31, 2020, in British Columbia, Canada. Any pregnant person at any gestational age living in BC was eligible to participate. We collected quantitative data using online survey tools, including the Edinburgh Postnatal Depression Scale (EPDS) and the 7-item Generalized Anxiety Disorder questionnaire (GAD-7). We collected qualitative data using open-ended questions to explore people's thoughts, feelings and experiences during the pandemic. Participants were recruited using study posters distributed via prenatal care clinics and classes, LifeLabs and social media across the province. We used thematic and descriptive analyses to analyze the data, and we integrated the qualitative and quantitative findings at the interpretation level.

RESULTS

The study sample included 96 participants with mean (± standard deviation) maternal and gestational ages of 32 ± 3.92 years and 22.73 ± 8.93 weeks, respectively. Most (93%; n = 89) identified as female. Of the participants, 54% (n = 50) and 35% (n = 34) reported anxiety and depressive symptoms, as measured by the GAD-7 and EPDS, respectively. Overarching themes that emerged from the qualitative data included uncertainty about birth plans and setting, added burden to existing health and social disparities, perceived or projected lack of support or limited support, concerns about early development, and struggle over managing multiple demands. Perceived maternity care needs included mental health support, maintaining prenatal care, frequent and proactive check-ins to build rapport, and recommendations specific to the pandemic.

INTERPRETATION

We found that the impact of the COVID-19 pandemic on the pregnant population has been substantial. The findings of this mixed-methods study can be used to help plan informed and evidence-based health care interventions to mitigate adverse effects and support mothers and families.

Experiences of Norwegian community midwives with caring for vulnerable pregnant women - A national cross-sectional study

OBJECTIVES

The study aimed to describe Norwegian community midwives' care for vulnerable pregnant women. It assessed vulnerability factors midwives identified and the type of care they provided. Factors associated with use of identification tools and care of vulnerable pregnant women were investigated.

METHOD

A quantitative, cross-sectional study. Data collected via an anonymous online survey conducted spring 2020. Of approximately 700 eligible community midwives in Norway, 257 (36.7%) participated.

RESULTS

Community midwives who worked primarily in the community, in close to full-time positions (>80%) and who were responsible for >100 women a year in large community clinics were more likely to identify vulnerable pregnant women than midwives who worked in combined hospital and community posts, less than 80% in the community and at smaller community centres. Attended a training progam called 'Early Start' (Tidlig Inn) was associated with an increased use of standardized identification tools. Almost all community midwives reported providing vulnerable women with more frequent consultations, individual and culturally personalized care, and relevant information about support options.

CONCLUSION

Community midwives appeared to be aware of their role as a midwife in the care of vulnerable pregnant women. They reported encountering vulnerable pregnant, identifying them by actively using methods to do so and addressing their needs in various ways. This study suggests that specific training increases midwives' ability to identify vulnerable pregnant women. Further research is needed to assess how midwives experience interdisciplinary collaboration in caring for these women.

Evaluation of psychological training for nurses and midwives to optimise care for women with perinatal depression: a systematic review and meta-analysis

Objective Perinatal depression is linked to poor maternal health and infant development outcomes. The World Health Organization recommends expanding the mental health education and training of primary care providers to improve the quality of perinatal depression care. The present study evaluated the effect of various psychological training methods on nurses' and midwives' competence in administering care to and alleviating symptoms in patients with perinatal depression. Methods A comprehensive search of the PubMed, MEDLINE, Cochrane Library, EMBASE, Web of Science, and CINAHL databases was performed. The data were independently extracted by two reviewers, and the critical appraisal tools of the Joanna Briggs Institute were used for quality assessment. Random-effects meta-analysis was conducted using Review Manager 5.4 software. Findings A total of 13 articles including 246 nurses and midwives and 4,381 perinatal women were reviewed. Care administered through both face-to-face (relative risk [RR] 0.70, 95% confidence interval [CI] 0.61-0.74) and digital training (RR 0.44, 95% CI 0.26-0.74) significantly mitigated symptoms of perinatal depression. Significant benefits were observed after 3- to 5-day and 8-day training, for which the RR were 0.75 (95% CI 0.59-0.97) and 0.72 (95% CI 0.66-0.85), respectively. Studies with high intervention fidelity more effectively reduced the risk of depressive symptoms in perinatal women than those with low intervention fidelity. Key conclusions and implications for practice Compared with face-to-face, digital training methods were more effective in reducing the risk of depressive symptoms. High intervention fidelity and 3- to 5-day and 8-day training resulted in better outcomes. The present findings can serve as a reference for the design of psychological training programs for nurses and midwives to equip them with effective strategies for administering care to patients with perinatal depression.

Are labor pain and birth experience associated with persistent pain and postpartum depression? A prospective cohort study

Background and aims A considerable research-literature focuses on pain during labor and associations with postpartum persistent pain and depression, with findings pointing in various directions. The aim of this study was to examine the role of labor pain and overall birth experience in the development of pain and depression 8 weeks after delivery. Methods The study sample was drawn from the Akershus Birth Cohort. Data from multiple sources were used, including the hospital's birth record (n = 4,391), questionnaire data from gestational week 17 of pregnancy (n = 3,752), 8 weeks postpartum (n = 2,217), and two questions about pain and birth experience asked within 48 h after delivery (n = 1,221). The Edinburgh Postnatal Depression Scale was used to measure postpartum depression, a single question was used to measure persistent pain 8 weeks postpartum, while pain and birth experience were measured by numeric rating scales. A history of pre-pregnant depression and chronic pain were measured through self-report questions in gestational week 17. A total of 645 women had complete data from all sources. We applied multiple imputation techniques to handle missing responses on the two questions about pain and birth experience. Results The results showed that neither labor pain nor birth experience were associated with persistent pain 8 weeks postpartum, whereas pain before pregnancy (OR 3.70; 95% CI 2.71-5.04) and a history of depression (OR 2.31; 95% CI 1.85-2.88) were statistically significant predictors of persistent pain. A negative birth experience was significantly (OR 1.16; 95% CI 1.04-1.29) associated with postpartum depression, whereas labor pain intensity was not. A history of depression (OR 3.95; 95% CI 2.92-5.34) and pre-pregnancy pain (OR 2.03; 95% CI 1.37-3.01) were important predictors of postpartum depression 8 weeks after delivery. Conclusions and implications Whilst the relationship between labor pain intensity and postpartum pain and depression remain unclear, our results do imply the need to screen for previous depression and chronic pain conditions in pregnant women, as well as consider preventive measures in those who screen positive.

Newborn white matter microstructure moderates the association between maternal postpartum depressive symptoms and infant negative reactivity

Maternal postpartum depression is a prominent risk factor for aberrant child socioemotional development, but there is little understanding about the neural phenotypes that underlie infant sensitivity to maternal depression. We examined whether newborn white matter fractional anisotropy (FA), a measure of white matter maturity, moderates the association between maternal postpartum depressive symptoms and infant negative reactivity at 6 months. Participants were 80 mother–infant dyads participating in a prospective population-based cohort, and included families whose newborns underwent a magnetic resonance/diffusion tensor imaging scan at 2–5 weeks of age and whose mothers reported their own depressive symptoms at 3 and 6 months postpartum and infant negative emotional reactivity at 6 months. The whole-brain FA moderated the association between maternal depressive symptoms and mother-reported infant negative reactivity at 6 months after adjusting for the covariates. Maternal depressive symptoms were positively related to infant negative reactivity among infants with high or average FA in the whole brain and in corpus callosum and cingulum, but not among those with low FA. The link between maternal depressive symptoms and infant negative reactivity was moderated by newborn FA. The variation in white matter microstructure might play a role in child susceptibility to parental distress.

Mid-Pregnancy Insomnia and its Association with Perinatal Depressive Symptoms: A Prospective Cohort Study

Objective/Background: Insomnia and depression are disorders that affect many perinatal women and that often are interrelated. The present study aimed to examine concurrent and prospective associations between mid-pregnancy insomnia and depression during mid-pregnancy and 8 weeks postpartum. Furthermore, differences in depression and in the sleep-related characteristics insomnia, chronotype, and sleep efficiency were explored between the two time points (mid-pregnancy versus 8 weeks postpartum), and between primiparous and multiparous participants.Participants/Methods: The study was part of the Norwegian population-based Depression and Anxiety in the Perinatal Period (DAPP) prospective cohort study. Among 539 women that were recruited for participation when receiving a routine ultrasound examination, we analyzed data from hospital birth records and questionnaire responses from pregnancy week 17 and postpartum week 8. We used the Edinburgh Postnatal Depression Scale to measure depression. The Bergen Insomnia Scale, the reduced Horne-Östberg Morningness-Eveningness Questionnaire, and three questions from the Pittsburgh Sleep Quality Index were used to measure the sleep-related characteristics.Results: Mid-pregnancy insomnia was significantly associated with concurrent depression (p < .001), but not with postpartum depression (p = .288), in a linear mixed model with adjustment for several reproductive and psychosocial variables. Sleep efficiency was reduced from mid-pregnancy to postpartum (from 88% to 77%), and primiparous women reported less efficient sleep than multiparous women after childbirth.Conclusions: The results indicate that mid-pregnancy insomnia may be a marker for concurrent depression but not a predictor of postpartum depression. Future research should examine the extent to which treatment of insomnia from mid-pregnancy on reduces both perinatal insomnia and depression.

Adverse Childhood Experiences are associated with choice of partner, both partners' relationship and psychosocial health as reported one year after birth of a common child. A cross-sectional study

Adverse Childhood Experiences (ACEs) are common and known to have consequences for individuals' adult health, leading to a higher risk of illness. The aims of the study were to investigate the ACEs in couples, to examine the extent of assortative mating and to investigate the association between the relationship of the load of ACEs within couples and health outcomes, one year after the birth of a common child. At antenatal clinics in Sweden 818 couples were recruited and investigated one year after the birth of a common child answering a questionnaire including the exposure to ten ACE categories and several outcome variables. In total, 59% of both mothers and partners reported exposure to at least one of the ten ACE categories. Among the mothers 11% and among the partners 9% reported exposure to ≥4 ACE categories (p = 0.12). There was a correlation between the numbers of ACE categories reported by the mothers and their partners (Spearman's ρ = 0.18, p<0.001). This association pertained to six of the ten ACE categories. In multiple logistic regression analyses, there were associations between the ACE exposure load and unfavourable outcomes among the mothers, the partners and within the couples. Unfavourable outcomes concerning health were most prominent in couples where both members reported exposures to ≥4 ACE categories (self-rated bad health (OR 13.82; CI 2.75-69.49), anxiety (OR 91.97; CI 13.38-632.07), depression (OR 17.42; CI 2.14-141.78) and perceived stress (OR 11.04; CI 2.79-43.73)). Mothers exposed to ACEs tend to have partners also exposed to ACEs. Exposure to ACEs was associated with bad health and unfavourable life conditions within the couples, especially among couples where both members reported exposure to multiple ACEs. These results should stimulate incentives to find, to support and to treat individuals and couples where both members report multiple ACEs. The consequences for the children should be further studied as well as how these families should be treated in health care and society.

Posttraumatic stress symptoms following childbirth: associations with prenatal attachment in subsequent pregnancies

This longitudinal population-based study aimed to investigate the prospective relationship between PTSD symptoms following childbirth and prenatal attachment in the subsequent pregnancy. Data were derived from the Norwegian Akershus Birth Cohort (ABC), a large population-based prospective cohort study. Data from 1473 women who had given birth at least once before and who had completed questionnaires at 17 and 32 weeks of gestation were included. Confirmatory factor analysis of the short version of the Prenatal Attachment Inventory was conducted to validate the scale. Further, structural equation modeling techniques were used to estimate prospective associations of PTSD symptoms following childbirth with prenatal attachment. Finally, to explore potential mechanisms of the association, mediation and moderation analyses were conducted. PTSD symptoms following previous childbirth were found to be prospectively related to higher levels of prenatal attachment in the subsequent pregnancy, while controlling for important confounding factors, such as symptoms of maternal depression and anxiety, previous pregnancy loss, and sociodemographic factors (maternal age, educational level, marital status, and number of children). When fear of childbirth was included as a potential mediating variable, the prospective relationship between PTSD symptoms following childbirth and prenatal attachment in the subsequent pregnancy increased, thereby indicating a suppressor effect. Fear of childbirth did not act as a significant moderator. Our findings suggest that a subsequent pregnancy following a traumatic childbirth may for some women represent an opportunity for a higher level of prenatal attachment, whereas high levels of fear of childbirth may be detrimental for prenatal attachment.

Paternal Psychological Stress After Detection of Fetal Anomaly During Pregnancy. A Prospective Longitudinal Observational Study

Background and Aims

Knowledge of carrying a fetus with a prenatal diagnosed anomaly may cause acute psychological stress to the parents. Most studies focus on maternal stress, yet fathers are often present at the ultrasound examinations and birth, and therefore may be affected, similarly, to the expectant mother. However, to date no existing studies have examined how detection of a fetal anomaly emotionally affects the expectant fathers throughout the pregnancy. Our aim was to longitudinally examine general health perceptions, social dysfunction and psychological distress in a subgroup of men where fetal anomaly was detected during pregnancy.

Methods and Results

This study is part of the SOFUS study, a prospective, longitudinal, observational study. Participants were recruited when referred for an ultrasound examination conducted by a specialist in fetal medicine at Oslo University Hospital on suspicion of fetal malformation (study group). We examined differences between the men in the study group (N = 32) and a comparison group (N = 83) on the General Health Questionnaire (GHQ), Impact of Event Scale (IES) and Edinburgh Postnatal Depression Scale (EDPS) across four time points in pregnancy. Results from repeated measured ANOVA suggests that depression decreased over time among men in both groups (η² = 0.15, p < 0.001). This effect was stronger in the study group, and differed from the comparison group (η² = 0.08, p < 0.001). There was also a main effect of time on IES scores, which decreased over time for both men in the study group and in the comparison group (η² = 0.32, p < 0.001). That is, men in the study group were higher on IES initially, but this effect decreased more in the study group than in the comparison group. Men in the study group and comparison group did not differ on perceived general health (GHQ: p = 0.864).

Conclusion

Results suggests that detection of a fetal anomaly has implications for paternal mental health during pregnancy. Expectant fathers scored higher on EPDS and IES than the comparison group in the acute phase after detection of fetal anomaly, thus there is impetus to provide psychological support for fathers, as well as mothers, at this difficult time.

Newborn Behavioral Observation, maternal stress, depressive symptoms and the mother-infant relationship: results from the Northern Babies Longitudinal Study (NorBaby)

BACKGROUND

Families can experience the postpartum period as overwhelming and many report a special need for support. The Newborn Behavioral Observation (NBO) aims to promote a positive parent-infant relationship by sensitising parents to the infant's signals. This article evaluates the NBO as a universal preventive intervention within the regular well-baby clinic service on measures of maternal depressive symptoms, parental stress, the mother-infant relationship and satisfaction/benefit of the postpartum follow-up.

METHODS

This investigation is part of a larger longitudinal study comprising 220 women and 130 of their partners recruited between 2015 and 2017. The study had a non-randomised cluster-controlled design with 6 measurement points. This article is based on a sample of 196 women using data from T1 (gestational weeks 13-39), T4 (5-15 weeks postpartum) and T5 (3-9 months postpartum). Participants were allocated to a group receiving the NBO (n = 82) and a care as usual comparison group (n = 114). We measured maternal depressive symptoms and parental stress using the Edinburgh Postnatal Depression Scale (EPDS) and the Parenting Stress Index (PSI). The mother-infant relationship was assessed with the Parental Reflective Functioning Questionnaire (PRFQ), the Maternal Postnatal Attachment Scale (MPAS) and the Maternal Confidence Questionnaire (MCQ). Participants also answered questions about satisfaction/benefit of the postpartum follow-up.

RESULTS

A Mann-Whitney U test indicated that participants in the NBO-group learned significantly more than the comparison group from the follow-up about the baby's signals in relation to sleep/sleep patterns, social interaction and crying/fuzziness. Multivariate analyses of covariance (MANCOVA) and repeated measures ANCOVA found no significant differences between the groups for the mother-infant relationship domain and few differences in depressive symptoms and parental stress. The repeated measures ANCOVA found that participants in the NBO-group scored slightly higher on parental stress, although the difference was small.

CONCLUSIONS

The results indicate that the NBO-group learned more than the comparison group about reading their child's signals in important everyday situations. However, the benefits of the NBO were limited for depressive symptoms, parental stress and self-reported mother-infant relationship. The study sample was generally well-functioning, and the results indicate that the benefits of the NBO may be limited within a well-functioning sample.

Parenting Stress Plays a Mediating Role in the Prediction of Early Child Development from Both Parents' Perinatal Depressive Symptoms

Maternal postnatal depression has been associated with a broad range of developmental risk among children. However, there has been less focus on disentangling the effects of pre- and postnatal depressive symptoms, as well as examining the symptoms of both parents. This study aims to investigate the separate effects of pre- and postnatal depressive symptoms in mothers and fathers, and parents' differential effects on child social-emotional, cognitive, and language development at 18 months of age. Further, we investigate whether effects of depressive symptomatology on child outcomes are particularly strong when both parents evinced high symptom loads and whether parenting stress mediates associations between perinatal depressive symptoms and child developmental outcomes. The study used data from 1036 families participating in a community-based study from mid-pregnancy until 18 months postpartum. Depressive symptoms were assessed at seven time points (four prenatally). Within a structural equation framework, we found that parental perinatal depressive symptoms predicted child social-emotional functioning, specifically externalizing, internalizing, and dysregulation problems, as well as language developmental delay at 18 months. Controlling for postnatal symptoms we found no independent effect of prenatal depressive symptoms on any child outcomes. A differential effect was evident, linking maternal symptoms to social-emotional outcomes, and paternal symptoms to language outcomes. There was no evidence of stronger associations between depressive symptoms and child outcomes when both parents showed high symptom loads. However, parenting stress mediated most relations between parental depressive symptoms and child outcomes. Findings demonstrate the importance of including paternal depressive symptoms in both clinical and research contexts.

Effects of supervised exercise training during pregnancy on psychological well-being among overweight and obese women: secondary analyses of the ETIP-trial, a randomised controlled trial

OBJECTIVES

Women with high body mass index (BMI) have increased risk for symptoms of anxiety and depression during pregnancy and postpartum. In this prespecified secondary analysis from the exercise training in pregnancy trial, our aim was to examine effects of supervised exercise during pregnancy on psychological well-being in late pregnancy and postpartum among women with a prepregnancy BMI ≥28 kg/m².

DESIGN

Single-centre, parallel group, randomised controlled trial.

SETTING

University Hospital, Norway.

PARTICIPANTS

Ninety-one women (age 31.2±4.1 years, BMI 34.5±4.2 kg/m²), 46 in the exercise group, 45 in the control group, were included in the trial.

INTERVENTION

The exercise group was offered 3 weekly supervised exercise sessions (35 min of moderate intensity walking/running and 25 min of resistance training), until delivery.

PRIMARY AND SECONDARY OUTCOMES MEASURES

Primary analyses were based on intention to treat, with secondary perprotocol analyses. To assess psychological well-being, we used the 'Psychological General Well-Being Index' (PGWBI) at inclusion (gestational week 12-18), late pregnancy (gestational week 34-37) and 3 months postpartum. We assessed postpartum depression using the 'Edinburgh Postnatal Depression Scale' (EPDS).

RESULTS

Numbers completed data collection: late pregnancy 72 (exercise 38, control 36), postpartum 70 (exercise 36, control 34). In the exercise group, 50% adhered to the exercise protocol. Baseline PGWBI for all women was 76.4±12.6. Late pregnancy PGWBI; exercise 76.6 (95% CI 72.2 to 81.0), control 74.0 (95% CI 69.4 to 78.5) (p=0.42). Postpartum PGWBI; exercise 85.4 (95% CI 81.9 to 88.8), control 84.6 (95% CI 80.8 to 88.4) (with no between-group difference, p=0.77). There was no between-group difference in EPDS; exercise 2.96 (95% CI 1.7 to 4.2), control 3.48 (95% CI 2.3 to 4.7) (p=0.55).

CONCLUSIONS

We found no effect of supervised exercise during pregnancy on psychological well-being among women with high BMI. Our findings may be hampered by low adherence to the exercise protocol.

Parent psychological wellbeing in a single-family room versus an open bay neonatal intensive care unit

Background

Studies of parents’ psychological well-being in single-family rooms in neonatal intensive care units have shown conflicting results.

Aims

To compare emotional distress in the form of depression, anxiety, stress and attachment scores among parents of very preterm infants cared for in a single-family rooms unit vs an open bay unit.

Study design

Prospective survey design.

Subject

Parents (132) of 77 infants born at 28 0/7–32 0/7 weeks of gestation in the two units.

Outcome measures

Duration of parental presence was recorded. Scores for depression (The Edinburgh Postnatal Depression Scale), anxiety (The State–Trait–Anxiety Inventory, Short Form Y), stress (The Parent Stressor Scale: neonatal intensive care unit questionnaire and The Parenting Stress Index—short form) and attachment (Maternal Postnatal Attachment Scale) measured 14 days after delivery, at discharge, expected term date and four months post-term.

Results

Parents were present 21 hours/day in the single-family room unit vs 7 hours/day in the Open bay unit. Ninety-three percent of the fathers in the single-family rooms unit were present more than 12 hours per day during the first week. Mothers in the single-family rooms had a significantly lower depression score -1.9 (95% CI: -3.6, -0.1) points from birth to four months corrected age compared to mothers in the Open bay unit, and 14% vs 52% scored above a cut-off point considered being at high risk for depression (p<0.005). Both mothers and fathers in the single-family rooms reported significantly lower stress levels during hospitalization. There were no differences between the groups for anxiety, stress or attachment scores after discharge.

Conclusion

The lower depression scores by the mothers and lower parental stress scores during hospitalization for both parents supports that single-family rooms care contribute to parents’ psychological wellbeing.

Mamma Mia - A randomized controlled trial of an internet-based intervention for perinatal depression

BACKGROUND

Studies suggest that 10-15% of perinatal women experience depressive symptoms. Due to the risks, problems with detection, and barriers to treatment, effective universal preventive interventions are needed. The aim of this study was to assess the effectiveness of an automated internet intervention ('Mamma Mia') on perinatal depressive symptoms. Mamma Mia is tailored specifically to the perinatal phase and targets risk and protective factors for perinatal depressive symptoms.

METHODS

A total of 1342 pregnant women were randomized to an intervention ('Mamma Mia') and control group. Data were collected at gestational week (gw) 21-25, gw37, 6 weeks after birth, and 3 and 6 months after birth. We investigated whether (1) the intervention group displayed lower levels of depressive symptoms compared with the control group, (2) the effect of Mamma Mia changed over time, (3) the effect on depressive symptoms was moderated by baseline depressive symptoms, previous depression, and parity, and (4) this moderation changed by time. Finally, we examined if the prevalence of mothers with possible depression [i.e. Edinburgh Postnatal Depression Scale (EPDS)-score ⩾10] differed between the intervention and control group.

RESULTS

Participants in the Mamma Mia group displayed less depressive symptoms than participants in the control group during follow-up [F(1) = 7.03, p = 0.008]. There were indications that the effect of Mamma Mia was moderated by EPDS score at baseline. The prevalence of women with EPDS-score ⩾10 was lower in the Mamma Mia group at all follow-up measurements.

CONCLUSIONS

The study demonstrated the effects of the automated web-based universal intervention Mamma Mia on perinatal depressive symptoms.

The association between the degree of nausea in pregnancy and subsequent posttraumatic stress

Hyperemesis gravidarum (HG) is a pregnancy condition characterised by severe nausea and vomiting during early pregnancy. The experience of HG is for many women a traumatic event. Few studies have investigated a possible association between HG and birth-related posttraumatic stress. The objective of the current study was to assess whether HG increases the risk of birth-related posttraumatic stress symptoms (PTSS). This was a population-based pregnancy cohort study using data from the Akershus Birth Cohort Study (ABC study). A linear mixed model was used to estimate the association between the degree of nausea (no nausea (n = 574), mild nausea (n = 813), severe nausea (n = 522) and HG (hospitalised due to nausea, n = 20)) and PTSS score at 8 weeks and 2 years after birth. At 8 weeks postpartum, women with HG had higher PTSS scores compared to women with no nausea (p = 0.008), women with mild nausea (p = 0.019) and women with severe nausea (p = 0.027). After 2 years, women with HG had higher PTSS scores compared to women with no nausea (p = 0.038). Women with HG had higher PTSS scores following childbirth compared to women with less pronounced symptoms or no nausea at all. After 2 years, women with HG still had higher PTSS scores compared to women with no nausea. Although the overall differences in PTSS scores were small, the results may still be of clinical relevance.

Latent trajectory classes of postpartum depressive symptoms: A regional population-based longitudinal study

PURPOSE

This study aimed to (a) assess trajectories of women's depressive symptoms during the first year postpartum to (b) identify potential unobserved classes of women as defined by their trajectories, (c) identify antepartum and early postpartum risk factors associated with trajectory classes, and (d) examine the association between trajectory classes and counselling during the postpartum period.

METHODS

Data on depressive symptoms, using the Edinburgh Postnatal Depression Scale (EPDS), were collected from 1374 women across nine Norwegian well-baby clinics at 1.5, 4, 6, and 12 months postpartum. Well-baby clinics offer universal, free services to all families living in the municipality. Thus, there were no specific exclusion criteria for this study. All clinics had implemented the Edinburgh-method which combines screening for PPD, using the EPDS, with supportive counselling.

RESULTS

Analyses showed that depressive symptoms decreased initially, followed by a flattening in symptoms at 6 months. Mixture analyses, however, identified two classes of women with distinct trajectories; (1) a low-risk (n = 1249, 91%) and (2) a high-risk group (n = 119, 9%). Complications after birth, elevated prenatal depressive symptoms, previous or current mental illness, and gestational week, predicted trajectory class membership. Women in the high-risk group were more likely to receive counselling than low-risk women.

LIMITATIONS

Women had higher educational level than the general population and one of the municipalities did not have a 12-months routine consultation.

CONCLUSION

Findings suggest heterogeneity among women in their depressive symptoms during the first year postpartum with a distinct set of risk factors associated with high-risk women. This has implications for the prevention and follow-up of women during pregnancy and the first year after childbirth.

Prevalence of postpartum depressive symptoms in a multiethnic population and the role of ethnicity and integration

BACKGROUND

Postpartum depression (PPD) may have adverse effects on both mother and child. The aims were to determine the prevalence of postpartum depressive symptoms, PPDS, identify associations with ethnicity and with the level of social integration.

METHOD

Population-based, prospective cohort study of 643 pregnant women (58% ethnic minorities) attending primary antenatal care in Oslo. Questionnaires regarding demographics and health issues were collected through interviews. PPDS was defined as a sum score ≥ 10 by the Edinburgh Postnatal Depression Scale, used as the main outcome in logistic regression analyses, first with ethnicity, second with level of integration as main explanatory factors.

RESULTS

The prevalence of PPDS was higher in ethnic minorities 12.7% (95% CI: 9.31-16.09) than in Western Europeans 4.8% (2.26-7.34). Adverse life events, lack of social support and depressive symptoms during the index pregnancy were other significant risk factors. Western European with PPDS were more likely to have had depressive symptoms also during pregnancy than women from ethnic minorities (72.2% versus 33.3%, p = 0.041). When replacing ethnicity with integration, a low level of integration was independently associated with PPDS (2.1 (1.11-3.95)).

LIMITATIONS

Cases with PPDS were limited. Heterogeneity in the ethnic groups is a concern.

CONCLUSION

Both point prevalence and new onset of PPDS was higher among ethnic minorities than among Western Europeans. Low level of integration was associated with PPDS. Our findings suggest that clinicians should be aware of the increased risk of new cases of PPDS among ethnic minorities compared to Western European women and offer evidence-based care accordingly.

PPD ACT: an app-based genetic study of postpartum depression

Postpartum depression (PPD) is one of the most frequent complications of childbirth and particularly is suited to genetic investigation as it is more homogenous than major depression outside of the perinatal period. We developed an iOS app (PPD ACT) to recruit, consent, screen, and enable DNA collection from women with a lifetime history of PPD to sufficiently power genome-wide association studies. In 1 year, we recruited 7344 women with a history of PPD and have biobanked 2946 DNA samples from the US. This sample of PPD cases was notably severely affected and within 2 years of their worst episode of PPD. Clinical validation was performed within a hospital setting on a subset of participants and recall validity assessed 6-9 months after initial assessment to ensure reliability of screening tools. Here we detail the creation of the PPD ACT mobile app including design, ethical, security, and deployment considerations. We emphasize the importance of multidisciplinary collaboration to correctly implement such a research project. Additionally, we describe our ability to customize the PPD ACT platform to deploy internationally in order to collect a global sample of women with PPD.

Physical activity in pregnancy and postpartum depressive symptoms in a multiethnic cohort

INTRODUCTION

There is strong evidence that postpartum depression is associated with adverse health effects in the mother and infant. Few studies have explored associations between physical activity in pregnancy and postpartum depression. We aimed to investigate whether physical activity during pregnancy was inversely associated with postpartum depressive symptoms, PPDS in a multiethnic sample.

METHOD

Population-based, prospective cohort of 643 pregnant women (58% ethnic minorities) attending primary antenatal care from early pregnancy to postpartum in Oslo between 2008 and 2010. Data on demographics and health outcomes were collected during standardized interviews. PPDS was defined by a sum score ≥10 from the Edinburgh Postnatal Depression Scale (EPDS), 3 months after birth. Physical activity was recorded with Sense Wear™ Pro3 Armband (SWA) in gestational week 28 and defined as moderate-to-vigorous intensity physical activity (MVPA) accumulated in bouts ≥10 min.

RESULTS

Women who accumulated ≥150 MVPA minutes/week had significantly lower risk (OR = 0.2, 95% CI: 0.06-0.90), for PPDS compared to those who did not accumulate any minutes/week of MVPA, adjusted for ethnic minority background, depressive symptoms in the index pregnancy and self-reported pelvic girdle syndrome. The results for MVPA persisted in the sub-sample of ethnic minority women.

LIMITATIONS

Numbers of cases with PPDS were limited. The SWA does not measure water activities. Due to missing data for SWA we used multiple imputations.

CONCLUSION

Women meeting the physical activity recommendation (>150 MVPA min/week) during pregnancy have a lower risk of PPDS compared to women who are not active during pregnancy.

A population-based study of the relationship between perinatal depressive symptoms and breastfeeding: a cross-lagged panel study

Studies suggest that perinatal depression and breastfeeding co-vary, but determining the relationship between breastfeeding and perinatal depression has proved challenging. A bidirectional association has been suggested, implying that depression may impact on breastfeeding and that breastfeeding might influence depressive symptoms. The present study aimed to contribute to the understanding of the relationship between perinatal depression and breastfeeding in a population-based sample where we used structural equation modeling (SEM) techniques to investigate cross-lagged and autoregressive effects as well as concurrent associations. The present study was part of a large-scale Norwegian prospective study. Nurses and midwives at nine well-baby clinics recruited participants. All the well-baby clinics had implemented the Edinburgh method, which combines the use of the Edinburgh Postnatal Depression Scale (EPDS) with an immediate follow-up conversation. Completed EPDS forms were recorded, as well as the mothers' reports of breastfeeding behaviors. Depressive symptoms measured prenatally during the last trimester, at 4 and 6 months postpartum did not predict breastfeeding behavior at 4, 6, or 12 months postpartum, respectively. Furthermore, breastfeeding at 4 and 6 months postpartum did not predict depressive symptomatology at 6 or 12 months postpartum. There were no significant concurrent associations between breastfeeding and depressive symptoms at 4, 6, or 12 months postpartum. Depressive symptoms predicted subsequent depressive symptoms and breastfeeding predicted subsequent breastfeeding. There was no evidence of a relationship between depressive symptoms and breastfeeding. Potential explanations and implications are discussed.

Optimal cut-off score of the Edinburgh Postnatal Depression Scale for major depressive episode during pregnancy in Japan

AIM

Depression during pregnancy adversely affects both mother and child. As antenatal depression is a predictor of postnatal depression, early detection might prevent postnatal depression. The Edinburgh Postnatal Depression Scale (EPDS) is frequently used during the perinatal period, but the cut-off score during pregnancy has not been verified for the Japanese population. We aimed to clarify the optimal EPDS cut-off score in mid-pregnancy in Japan.

METHODS

We recruited pregnant women aged 20 years or older at 12-24 gestational weeks and those who scored ≥9 on the EPDS were invited to participate in this study. In parallel with the EPDS, the Japanese version of the Mini-International Neuropsychiatric Interview was administered to determine diagnosis of major depressive episode. We then calculated the receiver-operator curve, sensitivity and specificity, and positive and negative predictive values for the EPDS.

RESULTS

All 210 participants were in the second trimester except for one (12 gestational weeks). Twenty participants were diagnosed with major depressive episode. With a cut-off score set at 13 points, the area under the curve was 0.956; sensitivity and specificity were 90.0% and 92.1% [Correction added on 10 November 2017, after first online publication: The percentage for specificity has been corrected from 79.0% to 92.1%.], respectively; and positive and negative predictive values were 54.5% and 98.9%, respectively.

CONCLUSION

To our knowledge, this is the first study to clarify the optimal EPDS cut-off score in the second trimester for Japan. This finding will be helpful for appropriate screening for antenatal depression in Japan.

Protocol for the Northern babies longitudinal study: predicting postpartum depression and improving parent-infant interaction with The Newborn Behavioral Observation

INTRODUCTION

Postpartum depression (PPD) is a prevalent disorder. Studying the factors related to PPD will help to identify families at risk and provide preventive interventions. This can in turn improve the developmental trajectories for the children. Several previous studies have investigated risk factors for PPD. However, few studies have focused on cognitive vulnerability factors. The first aim of the present study is to explore a range of protective and risk factors, including cognitive factors, for PPD, parent-infant interactions and child development. The second aim of the study is to evaluate the effectiveness of The Newborn Behavioral Observation (NBO) as a universal preventive intervention delivered in routine practice. The NBO is a brief relationship-enhancing intervention that may reduce depressive symptomatology in mothers.

METHODS

The study is a longitudinal observational study with an intervention. The observational study uses a prospective cohort design, whereas the intervention study has a non-randomised cluster-controlled design comparing a group receiving NBO with a group receiving standard care. The intervention group will receive three NBO sessions within the first 4 weeks postdelivery. Between 2015 and 2018, approximately 200 families will be recruited in the municipality of Tromsø, Norway. Parents are recruited during pregnancy, and assessments will be performed during gestational weeks 16-22, 24-30 and 31, and at 6 weeks, 4 months and 6 months postdelivery. Predictor variables include several cognitive vulnerability factors including early maladaptive schemas, implicit attitudes and cognitive processing of emotionally valenced infant facial information.

ETHICS AND DISSEMINATION

The Regional Committee for Medical and Health Research Ethics in Northern Norway has approved the project. The research team has collaboration with local health services and can assist participants who need more extensive follow-up. Results from the project will be disseminated in international and national peer-reviewed journals, and at courses and conferences.

Patterns and predictors of analgesic use in pregnancy: a longitudinal drug utilization study with special focus on women with migraine

Background

Few studies have investigated the drug utilization patterns and factors predicting drug use in pregnant women with migraine. This longitudinal drug utilization study aimed to describe patterns of analgesic use in a sample of Norwegian pregnant women according to their migraine history, and to identify predictors for analgesic use among these women.

Methods

Pregnant women giving birth at Akershus University Hospital between 2008 and 2010 were recruited at ultrasound examination in gestational week 17. Data were collected by questionnaires in gestational weeks 17 and 32, and at 8 weeks postpartum, and linked to birth records. Women were grouped into four categories according to migraine history: no migraine history, previous migraine history, recent migraine history (within 1 year prior to pregnancy) and migraine in pregnancy. Patterns of use of analgesics were analyzed descriptively. Multivariable logistic regression was used to identify factors predicting analgesic use.

Results

Out of 1981 women, 5.0% reported having migraine in pregnancy, 13.2% had a recent history of migraine, 11.5% had a previous history of migraine, and 68.8% reported no history of migraine. Analgesic use declined during pregnancy. Many women switched from triptans and non-steroidal anti-inflammatory drugs to paracetamol, which constituted most of the analgesic use. Factors associated with analgesic use included recent migraine history (OR 1.6, 95% CI 1.2–2.2), more severe headache intensity (OR 1.3, 95% CI 1.3–1.4), smoking (OR 1.9, 95% CI 1.1–3.3) and multiparity (OR 1.4, 95% CI 1.1–1.7).

Conclusions

Women with migraine stop or switch medications during pregnancy. Analgesic use in pregnancy is affected by migraine characteristics and intensity, and also by socio-demographic factors. Clinicians should bear this in mind when giving advice on adequate management of migraine in pregnancy and safe analgesic use.

Developmental pathways in infants from 4 to 24 months

BACKGROUND

There has been limited epidemiological research describing population-based samples regarding developmental pathways throughout infancy, and the research that exists has revealed substantial diversity. Identifying predictors for developmental pathways can inform early intervention services.

METHODS

The Ages and Stages Questionnaire was used to measure communication, gross motor, fine motor, problem-solving and personal-social skills longitudinally in a large, population-based sample of 1555 infants recruited from well-baby clinics in five municipalities in southeast Norway. We conducted latent class analyses to identify common pathways within the five developmental areas.

RESULTS

Our results indicated that most classes of infants showed generally positive and stable normative developmental pathways. However, for communication and gross motor areas, more heterogeneity was found. For gross motor development, a class of 10% followed a U-shaped curve. A class of 8% had a declining communication pathway and did not reach the level of the high stable communication class at 24 months. Low gestational age, low Apgar score, male sex, maternal depression symptoms, non-Scandinavian maternal ethnicity and high maternal education significantly predict less beneficial communication pathways.

CONCLUSION

The results suggest that infants with low gestational age, low Apgar score, male sex and a mother with depression symptoms or non-Scandinavian ethnicity may be at risk of developing less beneficial developmental pathways, especially within the communication area. Targeting these infants for surveillance and support might be protective against delayed development in several areas during a critical window of development.

Maternal psychological responses during pregnancy after ultrasonographic detection of structural fetal anomalies: A prospective longitudinal observational study

In this longitudinal prospective observational study performed at a tertiary perinatal referral centre, we aimed to assess maternal distress in pregnancy in women with ultrasound findings of fetal anomaly and compare this with distress in pregnant women with normal ultrasound findings. Pregnant women with a structural fetal anomaly (n = 48) and normal ultrasound (n = 105) were included. We administered self-report questionnaires (General Health Questionnaire-28, Impact of Event Scale-22 [IES], and Edinburgh Postnatal Depression Scale) a few days following ultrasound detection of a fetal anomaly or a normal ultrasound (T1), 3 weeks post-ultrasound (T2), and at 30 (T3) and 36 weeks gestation (T4). Social dysfunction, health perception, and psychological distress (intrusion, avoidance, arousal, anxiety, and depression) were the main outcome measures. The median gestational age at T1 was 20 and 19 weeks in the group with and without fetal anomaly, respectively. In the fetal anomaly group, all psychological distress scores were highest at T1. In the group with a normal scan, distress scores were stable throughout pregnancy. At all assessments, the fetal anomaly group scored significantly higher (especially on depression-related questions) compared to the normal scan group, except on the IES Intrusion and Arousal subscales at T4, although with large individual differences. In conclusion, women with a known fetal anomaly initially had high stress scores, which gradually decreased, resembling those in women with a normal pregnancy. Psychological stress levels were stable and low during the latter half of gestation in women with a normal pregnancy.

Insomnia before and after childbirth: The risk of developing postpartum pain-A longitudinal population-based study

OBJECTIVE

To examine if insomnia before and after childbirth predicts the development of postpartum bodily pain.

METHODS

This study is part of a longitudinal cohort study, the Akershus Birth Cohort Study, which targeted all women giving birth at Akershus University Hospital in Norway. The current sample is comprised of 1480 women who participated at all three time points, yielding a participation rate of 32% of the 4662 women who originally consented to participate. The Bergen Insomnia Scale (BIS) was used to measure insomnia and a latent profile analysis (LPA) was used to identify subsets of women who shared a similar pattern of responses on the BIS-scale across the three time points. Pain was measured using the bodily pain scale, derived from the Primary Care Evaluation of Mental Disorders (PRIME-MD) and symptoms of depression were measured by the Edinburgh Postnatal Depression Scale (EPDS).

RESULTS

Using a latent profile analysis a three class model showed the best fit and identified one major group (55.6%) with a low BIS scores across all three time points, one group with intermediate BIS scores (32.9%), and a smaller group (11.5%) with higher BIS scores across all three times. The chronic high insomnia group had a 2.8-fold increased risk of reporting high levels of bodily pain. The chronic intermediate group was associated with a 2.2-fold increased risk of bodily pain at two years postpartum. Adjusting for demographics and lifestyle behaviors did not reduce any of the associations, while adjusting for depression significantly attenuated the associations. Additional adjustment for pain at eight weeks postpartum further reduced the magnitude of the associations, but both chronic intermediate insomnia and chronic high insomnia remained strongly associated with the onset of bodily pain in the fully adjusted models (RR=1.75, 95% CI: 1.37-2.23) and RR=1.63, 95% CI: 1.15-2.32, respectively).

CONCLUSIONS

The high prevalence of insomnia among women during and after childbirth, in combination with the strong prospective association with impaired physical health, emphasizes the importance of adequately identifying, preventing and treating insomnia for this population.

Association between maternal postnatal depressive symptoms and infants' communication skills: A longitudinal study

Postnatal depression (PND) is associated with adverse effects on a broad range of child outcomes, including language problems. The current study aimed to investigate if the time of exposure to maternal PND symptoms measured with the Edinburgh Postnatal Depression Scale (EPDS) at 6 weeks, 4 months and 6 months postpartum were related to the infants' communication skills measured with the Ages and Stages Questionnaires (ASQ) at 12 and 24 months. Secondly, to study to what extent the number of exposures to high level of PND symptoms (i.e., EPDS score≥10) might be associated with level of communication skills later (at 12 and 24 months), and last, to determine to what extent maternal PND symptoms at 6 weeks were related to changes in the developmental course of communication skills from 4 to 24 months. 1555 children and their mothers participate in the study. Regression analyses indicated that PND at 4 months were associated with lower levels of communicative skills at 12 (coefficient -0.37, 95% CI -0.63 to -0.12, p=0.004) and 24 months (coefficient -0.34, CI -0.56 to -0.13, p=0.002). Infants of mothers with an EPDS sum score≥10 obtained at a minimum of two time points, had significantly worse communicative skills at 12 months than infants of mothers with no indication of PND (difference -6.12, CI -11.14 to -1.09, p=0.017). No such significant relations were found at 24 months. However, linear mixed effects analysis showed that mothers' depressive symptoms at 6 weeks were not significantly related to changes in infant communication scores from age 4 to 24 months. These findings suggest that symptoms of maternal PND symptoms should be taken into account for communication development in infancy.

Self-reported short sleep duration and insomnia symptoms as predictors of post-pregnancy weight change: Results from a cohort study

This study aims to investigate whether change in sleep duration and insomnia symptoms in the postpartum period is related to change in body mass index from before to 2 years after pregnancy. This study is based on self-report data from a Norwegian cohort, the AHUS Birth Cohort Study. Data were collected at 8 weeks (T1) and 2 years (T2) postpartum. Data from 812 women were analyzed. The results showed that only women with symptoms of insomnia at both T1 and T2 (persistent symptoms) had a greater increase in body mass index compared to women with no insomnia symptoms at T1 or T2.The results indicate that persistent insomnia symptoms are related to a greater increase in body mass index.
